Copernicus likely kept his theory of heliocentrism to himself out of fear of backlash from the prevailing religious and scientific authorities of his time, who favored the geocentric model. He may have also wanted to further refine his theory and gather more evidence before presenting it to the public.
Nicolaus Copernicus disagreed with his theory, Copernicus belived that Ptolemy's view was to complicated.
The theory of cosmology that Copernicus proposed is called the heliocentric theory. This theory placed the Sun, rather than the Earth, at the center of the solar system, with the planets orbiting around it.
Nicolaus Copernicus was the promoter of the heliocentric theory, which states that the Earth and other planets revolve around the Sun. He published his theory in his book "De revolutionibus orbium coelestium" in 1543.
Shortly before Copernicus died he figured that the Earth was notthecenter of things, but the Sun was. This theory is still used today. He worked out this this theory from detailed observations of the orbit of Mars.
Copernicus developed an interim theory of the planets in which the Sun was at the centre instead of the Earth as had previously been believed. Although Copernicus's theory only lasted from 1543 to 1609 when Kepler's theory replaced it, it is regarded as a useful step along the way.
Copernicus' theory was that Earth is not the center of the universe and we revolve around the Sun.

Galelei derived his theory from Copernicus. To Copernicus it was just a theory. Galilei managed to prove it when he invented the telescope and was able to see the moons orbiting Jupiter.

Copernicus was the first to propose the Heliocentric theory, the correct theory that the Sun, not the Earth, is the center of the solar system.
Copernicus discovered the heliocentric theory in 1510 and worked on it for four more years.
heliocentric theory
copernicus coined the heliocentric theory...
YES!
Galileo
Nicholaus Copernicus was one of the first to challenge the theory that the earth was the center of the universe. He made up the Heliocentric theory.
